The compound from each of the three pairs that undergoes E2 elimination faster is to be predicted. Concept Introduction: > E2 elimination involves the substrate as well as the base in the rate determining step. > The base extracts a proton in β-position to the halogen. Simultaneously, the C - H bond pair moves to form the C − C pi-bond and the halogen (X)leaves along with the C − X bond electron pair. > E2 elimination exhibits (deuterium) the isotope effect because the C - H or C - D bond is broken in the rate determining step.
